Hive: Convert String to Integer

I am looking for a Built-in UDF to convert values of a string column to integer in my hive table for sorting using SELECT and ORDER BY. I searched in the Language Manual, but no use. Any other suggestions also welcome.

cast(str_column as int)

From: Language manual UDFs - type conversion functions

If the value is between –2147483648 and 2147483647, cast(string_filed as int) will work. else cast(string_filed as bigint) will work

    hive> select cast('2147483647' as int);
    OK
    2147483647
    
    hive> select cast('2147483648' as int);
    OK
    NULL
    
    hive> select cast('2147483648' as bigint);
    OK
    2147483648
